WINDUW SASH AND VENTILA'I'OR.

Specification of Letters Patent. Patented Sept. Lilli, 191?.

Application filed November 6, 1915. Serial No. 60,034.

, To all'wkom it may concern:

Be it known that I, FRANK VIc'roR, a citizenof the United States, residing at Ridg way, in the county of Elk and State of Pennsylvania, have invented a new and useful Window Sash and Ventilator, of which the following is a specification.

This invention relates to an improvement in a combined window sash and ventilator, and the object is to provide means for ad- -mitting fresh air to a room through the lower rail of the lower sash without the necessity of raising the sash, the provision of said means causing the air to be directed upwardly to overcome any possibility of drafts. I

A further object is inthe provision of a straight edge on the bottom of the sash rail, instead "of providing the beveled surface, to prevent moisture and the like from being retained between the sash rail and sill, and overcome the objection of allowing the moisture to remain between the sill and sash and'cause them to decay. 7

It is a further aim of the invention to provide a connection between the lower rail of a sash and the side rails thereof so as to carry the enlarged lower. rail and the ventilating parts, and at the same time to provide a joint or connection which will exclude moisture and consequent deterioration by reason of access of moisture to the glue necessary in securing sash joints. a

The invention consists of certain novel features of construction and combination of parts which will be hereinafter described 7 and pointed outin the claim. It is evident that-changes in the form, proportion, material and minor details of construction within the scope of the appended claim, may be made without departing from the spirit or sacrificing any of the advantages of the invention. j

Fig. 7 is a transverse sectional view on tin:i line 7-7 of Fig. 3 on a reduced scale; an

Fig. 8 is a horizontal sectional view of one corner of the sash frame and easing therefor, the section being taken on the line 88 of Fig. 5.

Fig. 9 is a detail perspective View of a portion of the lower sash rail.

A, represents a window frame in which is mounted the lower rail 1, and side rails 2 of a lower sash. A window pane 3 is held in place on the side and lower rails.

The lower sash rail has the lower edge or bottom surface thereof cut oil straight producing a straight edge 4, so that'a space,

say of one-fourth of an inch, is formed between the sill 5 of the window frame and the lower surface of the sash rail 1. This space will prevent moisture, rain and snow from being retained between the sill and lower rail which would tend to cause the lower rail and sill to decay. Two spaced horizontal transverse openings 6 are formed in the lower rail, which extend inwardly and are slightly inclined in an upward direction. The rail 1 is rabbeted at its lower inner edge and rests thereat upon the sill, or sill cap 8, as shown in Fig. 4:, and is enlarged or thickened transversely, as at B, so as to extend inwardly beyond the plane of the inner face of the sash to accommodate the ventilator features of this invention. The ends of the rail terminate adjacent to the beads 9, and are of a length topermit the enlarged lower rail to slide vertically without injuring or interfering with the beads 9.

From Figs. 5 and 8 of the drawings, it

will be. noted that the improved joint or connection between the lower rail 1 and the side rails 2 comprises a'tongue 19 co-extensive in length with the lower rail 1 at each ends the overlapping portion of the lower rail and are introduced fromthe outside of the sash inwardly.

That portion of the rail 1 projecting inwardly beyond the plane of the inner face of the sash has vertical openings-or passages 10, to communicate with the horizontal openings 6. The openings 10 extend vertically so that the air will be discharged into the room in an upward direction, and not in a horizontal direction. A strip or plate 11 is mounted on the upper surface of the rail, and is received in a mortise or recess so that it is flush with the upper surface of the rail. The strip or plate 11 is fastened in position by means of glue and a screw 12, and is preferably of wood, to conform-to the material'of which the rail is constructed. The strip or plate is provided with a plurality of apertures or orifices 13 through which the air is admitted to the room. Located beneath the strip or plate, is a metallic damper bar 14, which is provided with a plurality of apertures or orifices 15, which are adapted to be brought into registry with the apertures 13 of the strip or plate '11 to admit air to the room. The rigid plate 11 is longer thali the sliding damper 14 as shown in Fig. 3. The damper is supported intermediately of its ends upon the solid por-- tion of the rail which divides the pair of ventilating openings from each other, and at its ends the damper moves in recesses in the rail beyond the said openings. The rigid plate does not rest with its entire weight upon the damper, as said plate is supported at its ends in separate recesses, which are made in the solid portion of the rail above the recesses provided for the ends of the damper. By this construction the damper is capable of sliding back and forth without binding or friction.

When the damper is movedin an opposite direction the apertures of the plate 11 will be close thereby shutting off the ingress of air to the room.

g A button or plate 16 is mounted to slide on the strip or plate 11 with the damper, and is connected to the damper 14 by means of a rivet or other fastening 17, so that upon the actuation of the button lfijthedamper will be operated. v

The openings 6 and 10 of the lower rail are in communication with each other, and when the air is discharged from the openings 10 it is through the apertures formed in the strip or plate 11. As the rail 1 is rabbeted at its lower inner edge, .the rail will engage the outer vertical wall of the sill cap 8, and will also rest upon the sill cap, forming an air and water tight joint which. is angular as shown.

The openings 6 and. 10 are spaced apart longitudinally in the bar B to provide a central reinforcement or bridge portion be tween the openings, which, as shown in Fig. 7, forms an ample support for the sash lift 18, which is set into the bar B for the purpose of raising and lowering the sash.' With this construction, the openings 6 and 10 may extend substantially throughout the entire prevent air and rain from entering the room beneath the sash, and in which the sash will not be affected by snow, water and the like, which might enter beneath the sash.

Furthermore, air may be admitted to the room at any time! without icreating ,any drafts, as the air is caused to travel through the angular openings, formed b zontal and vertical openings 0 the lower rail, in an upward direction, and the amount of air admitted'to the room can be regulated by thedamper 14.

As the ventilator can be operated without raising the window sash, which is necesthe horisary in some types of ventilators,'the room may be ventilated without unlocking the window. It is well known that in those types of ventilators which 'are inserted beneath the rail of the lower sash, the sash must be unlocked and kept in that condition, as long as the'ventilator is in place.

One of the points of advantage of this invention is the extra strength imparted to the lower rail of the lower sash by the addition of the enlargement B. The enlargement of the rail is on the inside to provide suflicient space for the draft regulator and to position the same for easy access,-and adjustment. The joint between each side rail and the adjacent end of the lower rail is such that it rovides a rigidconnection between the rails, holds the sash from sagging, and excludes moisture fromthe' glue and dowels so that the life of the sash, and the.

ventilator is materially prolonged.

By positioning the ventilator in the lowerrail of the sash, moisture accumulating on hatchet the window panes will trickle down upon the lower sash rail and, entering the openings 10, will pass out through the openings 6. In this way, moisture is prevented from running onto the floor. The objectionable steaming or freezing in cold weather will be obviated.

The enlargement B and the window sash are integrally constructed of wood, although they may be formed in any other desired manner and of any suitable material. It is possible with the use of the enlargement B to form a recess therein for the reception of the sash lift 18, thereby eliminating the objectionable outside lifts which must be attirched to the inner surfaces of the sash r31 2 What is claimed is:

In a ventilator, a sash having its bottom rail transversely enlarged and formed with angular openings therethrough which lead from the outside to the upper inner edge of the rail, said openings being spaced apart substantially midway of said bottom rail to leave a solidportion of the rail which divides said openings .from each other, a damper having a pluralityof openings and supported intermediately of its ends upon said solid portion of the rail and having its ends moving in recesses in said rail be yond said openings, a rigid plate also pro vided with openings and arranged above the damper and supported at its ends independently thereof, said damper and said plate being located at the upper inner edge openings, and a sash lift set into the front side of the rail at the intermediate solid of the rail at the inner terminal of said Y
